Abstract

The invention discloses a petal-shaped nanofiber production device and method. The device includes a petal-shaped spinning nozzle for spraying the spinning solution into a spinning jet, a high-voltage spinning power supply for generating static electricity from the petal-shaped spinning nozzle and a spinning nozzle for collecting the sprayed out of the petal-shaped spinning nozzle. Nanofiber collection device for silk jets. The production method is as follows: fill the spinning liquid in the petal-shaped spinning nozzle; turn on the high-voltage spinning power supply and adjust the spinning voltage; the spinning jet is excited from the surface of the petal-shaped spinning nozzle; the nanofiber collecting device receives the continuous spinning jet , that is, nanofibers. The petal spinning nozzle adopted in the present invention can generate equal jet stretching electric field force at the tip of the nozzle, and at the same time greatly increase the number of electrospinning jets generated, and can obtain nanofiber aggregates with very uniform diameters.

Description

technical field [0001] The invention relates to a petal-shaped nanofiber production device and method, belonging to the field of nanofiber production. Background technique [0002] With the research and development of nanotechnology, electrospinning technology, which can quickly obtain fibers with a diameter distribution from several nanometers to several micrometers, has developed rapidly in the past 20 years. The nanoscale fiber prepared by it has a large specific surface area, rich pore structure, flexible surface functionalization characteristics and superior interface and surface effects. Electrospinning technology is therefore widely used in energy, environment, biological science, medical engineering, military and national security and other fields. [0003] Existing electrospinning devices mainly include traditional single-needle electrospinning devices and new needle-free electrospinning devices. The traditional single-needle electrospinning device is mainly compo...
